China SK-500 Belt Tension Meter - Accurate Measurement for V, Flat, and Ribbed Belts from Leading Suppliers and Factory
Advanced Optical Measurement Technology
The SK-500 utilizes an advanced optical measuring principle. By simply tapping the non-moving belt to induce oscillation, the integrated red LED light source precisely determines the natural frequency of the strand vibration. Unlike acoustic-based meters, the SK-500’s readings are completely unaffected by ambient noise or nearby magnetic fields, ensuring reliable data even in the busiest factory environments.
The unit displays readings clearly on an easy-to-read LCD screen in your choice of frequency (Hz) or actual strand force (Newtons or pound-force). To calculate force values, the meter allows for the input of two critical parameters: free strand length (up to 9.99 meters) and belt mass (up to 9.999 kg/m). This flexibility makes the SK-500 an indispensable tool for a wide variety of drive setups.
Designed for Versatile Field Use
Understanding that access to belts can often be restricted, the SK-500 comes equipped with two distinct probe options. Use the plug-in probe for convenient one-hand operation during routine inspections. For confined spaces where the display unit cannot fit directly over the belt, simply attach the included probe with cable to take measurements in limited access areas with ease.
The user interface is designed for global operation with a multi-language menu, and the rugged, compact ABS plastic housing protects the internal microprocessor from the rigors of daily industrial use. Powered by a standard 9V battery, this lightweight instrument (approx. 170g) is fully portable.

Frequently Asked Questions
How does the SK-500 measure belt tension?
It uses an optical sensor (red LED) to detect the vibration frequency of the belt strand after it is tapped. This frequency is then used to calculate the tension based on the belt's mass and length.
Is the SK-500 affected by loud factory noise?
No. Unlike acoustic tension meters that rely on sound, the SK-500 uses optical sensing, making it completely immune to ambient noise and magnetic interference.
Can I measure tension in tight or hard-to-reach spaces?
Yes. The SK-500 includes both a standard plug-in probe for one-handed use and a flexible cable probe specifically designed for measurements in confined areas.
What units of measurement are available?
The device can display results in Frequency (Hz), Newtons (N), or Pound-force (lbf), providing flexibility for different engineering standards.
What is the required sensing distance for accurate readings?
For optimal results, the probe should be held at a distance of 3 mm to 20 mm from the belt strand.
What parameters do I need to input for tension calculation?
You need to enter the belt's free strand length (up to 9.99m) and the belt's unit mass (up to 9.999 kg/m).
